Tuning a clarinet

On a clarinet you tune mainly with the barrel, which is the short joint below the mouthpiece. Warm up, then play a steady note.

  • Needle left (flat): push the barrel in.
  • Needle right (sharp): pull the barrel out slightly.

If the long, low notes are out of tune but the upper ones are fine, adjust the middle tenon instead. This is where the upper and lower joints meet.
